Dwarf Planet Series Mono Guiding Camera

The Player One Xena 585M is a compact mono guide camera built around the Sony IMX585 sensor with STARVIS 2 back-illuminated technology. Designed for precision autoguiding and high-speed capture, it pairs a large 1/1.2" sensor with a true 1.25" form factor for clean, responsive performance in portable rigs.

Sony IMX585 Sensor (STARVIS 2)

Xena 585M adopts the Sony IMX585 monochrome CMOS sensor. STARVIS 2 improves low-light performance, supporting more reliable guide-star acquisition and excellent response in short-exposure imaging.

• Sensor format: 1/1.2"
• Resolution: 8.3MP (3856 × 2180)
• Pixel size: 2.9 µm
• Full well: 47 ke⁻
• Diagonal: 12.85 mm
• Peak QE: approx. 91%

Highlights

• USB 3.0 (5Gbps): high-speed data transfer for responsive guiding and fast capture.
• True 1.25" body: slides directly into standard 1.25" guide scope adapters.
• CS-mount flexibility: compatible with 5–100mm CS lenses for guider/finder use.

Stable High-Speed Capture

With USB 3.0 connectivity, the Xena 585M can reach up to 47 FPS at full resolution in RAW8 (10-bit ADC). Actual recording speed depends on storage performance; a quality SSD is recommended.

HDR Mode (IMX585 Feature)

HDR (High Dynamic Range) mode increases dynamic range and can reduce read noise, supporting improved results in high-contrast scenes (particularly useful for short-exposure DSO imaging and bright-star fields).

DPS – Dead Pixel Suppression

Player One’s DPS technology analyses multiple dark frames to map fixed abnormal pixels. During capture, affected pixels are corrected using surrounding pixel data for cleaner frames.

• USB 3.0 data port
• ST-4 guiding support (connect to the mount’s AUTO GUIDE port)
